FIG. 1.
Presence of hyphae in cellulose baits placed in Esthwaite Water. Gray and white columns represent numbers of micromonosporas recovered from the baits (103 CFU per g cellulose bait) before and after heat treatment, respectively. A decrease in CFU numbers after heat treatment is indicative of the presence of hyphae in the samples, which can be observed with strong confidence in the surface, 3-m, and 7-m samples. Baits placed deeper in the water column and sediment also showed evidence for the presence of hyphae, but this was not statistically significant.
